Date Jul. 27, 1989.A heating and/or cooling system incorporates a number of modular refrigeration units each of which includes at least one compressor, an evaporator and a condenser. A variable speed circulating water pump circulates water through each evaporator/condenser, which are connected in parallel across the respective supply line and return line. A master controller activates and deactivates individual compressors in accordance with load demand. Shut-off valves close off the water flow through the respective evaporator and/or condenser of any units deactivated and the resulting changes in the pressure differential in the supply and return lines is sensed by sensor which sends a signal to the pump motor speed controller which changes the output of the pump to restore a predetermined pressure differential.

Abstract: A method and apparatus is described for transmitting and receiving data signals and voice band signals over a single pair of wires, wherein the energy content of the data signals in the voice bands is transferred to a higher frequency to avoid interference between the two. This is accomplished by sinusoidally encoding the data pulses in the frequency domain. The encoding is equivalently performed in the time domain by linearly combining weighted delayed and advanced versions of the data pulses, in accordance with a weighting formula. A transversal filter is used to multiple delayed and advanced versions of the data pulses by a scaling factor times the ratio of m!/(m-i)!i! factorial wherein i is the ith version being weighted, m is an integer greater than one and ! indicates the factorial function.

Abstract: The sealing strip has two anchoring lips (1, 2), with which it can be anchored in the groove, which fits it, of a frame, and also a sealing lip (5). This seals with its outermost part, the tip (13), by bearing against a wing. In order to be able to guide the strip around the corners of the frame during mounting on the same, a notch (9) is made in the usual way, which makes possible bending by 90 DEG . In order that, during this bending, no material accumulations occur on the sealing lip in those places where it is supposed to seal, it is arranged in such a manner that it extends from a place close to one anchoring lip (2) in such a direction that its tip (13) is situated essentially in the region of the outer side (6a) of the lip base (6). During bending, the bowed piece (16) of the sealing lip tip (13) thus created has approximately the same length as the corresponding straight section before. As a result, material accumulations are avoided and this tip bears over its entire length against the wing without buckling so that a reliable seal is guaranteed. <IMAGE>

Abstract: The boiler consists of a water-bearing housing (3) with, arranged in the upper part, an essentially horizontally oriented combustion chamber (1), from which heating gas flues (4) are conducted to a waste gas and condensate collecting chamber (20) with waste gas connection pipe pieces (24), which is arranged at the bottom on the housing, the heating gas flues (4) and their mouths being connected to the combustion chamber (1) in the region distant from the burner. In order both to simplify such a boiler, which is in particular intended for operation as a condensate boiler, with regard to manufacturing technology, but also in particular to ensure optimum flow conditions both on the firing side and on the water side in the transition region from the upper part to the lower part, the housing part (2) containing the combustion chamber (1) and thus the combustion chamber (1) itself and the housing part (6) of the water-bearing housing (3) containing the heating gas flues (4) are joined together in a common bevel-cut plane (7), in which a correspondingly inclined plate (9) with heating gas flue openings, which forms the burner-distant bottom (8) of the combustion chamber (1) is arranged. To this plate (9), the heating gas flue ends (4') are connected in a liquidproof manner, and furthermore the water-bearing inner spaces (2', 6') of the two housing parts (2, 6) are interconnected. <IMAGE>

Abstract: A non-contacting gas sealing device for a shaft (1) - having a seal housing (2), a stator seal ring (3) arranged in the seal housing (2), and a rotor seal ring (4) arranged on the shaft (1) and fixed to it. The two seal rings (3)(4) interact by means of their seal end faces (3a)(4a) with the interposition of the gas barrier. In the operating condition and under a predetermined differential operating pressure, the stator seal ring (3) has an annular functioning gap (F) relative to a shaft-side cylindrical part of the seal housing (2), the said gap being sealed by a rubber or plastics O ring seal (11) arranged in a groove and being pressed against the gas barrier with a contact pressure determined by at least one pressure spring (7). The stator seal ring (3) also consists of a hard seal material with a high thermal conductivity, a high modulus of elasticity and great hardness. The stator seal ring (3) has such a large geometrical moment of inertia that, in the operating condition and under a differential operating pressure, the thickness of the annular functioning gap between the shaft-side cylindrical part of the seal housing and the stator seal ring virtually coincides with the corresponding structurally predetermined annular assembly gap between the cylindrical part and the stator seal ring (3) in all operating conditions and is smaller than 0.4 mm, preferably less than 0.3 mm. The O ring seal is additionally designed as a compensating centring ring for the stator seal ring (3) and, for this purpose, has a hardness which is greater than the extrusion limit for the hardness of the material at the gap width specified and the predetermined differential operating pressure and is smaller than the hardness figure of 90 Shore A according to DIN 53 505. <IMAGE>

Abstract: A start-up coupling engages progressively in two stages. During the first stage drive is transmitted from an input shaft (3) along respective paths (8,7,9,12,11,10,25 and 26; and, 19,20,19 and 32) to helically-toothed rollers ( 2 7 , 30 ) which mesh but are designed to be incapable of transmitting drive between them, or of doing so very inefficiently. The rollers (27,30) are mounted in an oil-filled chamber (18) in a casing (1) integral with an output shaft (2). During the first hydraulic stage of engagement, oil pockets between their oppositely-moving teeth (28,31) prevent them from engaging as the phase of one roller (27) is progressively changed by a centrifugal adjustment (4) against the bias of a torque cell (19). However, increasing frictional resistance in the oil pockets causes the rollers (27,30) to exert an increasing rotational torque on the casing (1). Simultaneously, the relative movement of the roller teeth diminishes to reduce the hydraulic pressure in the pockets to a level where the pockets collapse. This initiates the second stage of engagement when drive is transmitted through the coupling mechanically by way of rubbing of the roller teeth (28,31). This rubbing ceases when engagement of the coupling is completed. Tooth wear is lessened by the two stages of engagement.
